Concept:Mechanization has both advantages and limitations; one limitation is its effect on soil exposure.
Explanation:Mechanization involves using machines like tractors and ploughs for farm operations.
It can disturb the soil surface and remove vegetation cover.
This leaves the soil exposed to wind, rain, and other climatic elements.
As a result, the soil becomes more prone to erosion and loss of fertility.
Therefore, exposure of soil to the effects of climate is a major limitation of farm mechanization.
Answer:B. exposure of soil to the effects of climate
